Molecular Layer-by-Layer Assembled Thin-Film Composite Membranes for Water Desalination

Molecular layer‐by‐layer (mLbL) assembled thin‐film composite membranes fabricated by alternating deposition of reactive monomers on porous supports exhibit both improved salt rejection and enhanced water flux compared to traditional reverse osmosis membranes prepared by interfacial polymerization....

Zusammenfassung:Molecular layer‐by‐layer (mLbL) assembled thin‐film composite membranes fabricated by alternating deposition of reactive monomers on porous supports exhibit both improved salt rejection and enhanced water flux compared to traditional reverse osmosis membranes prepared by interfacial polymerization. Additionally, the well‐controlled structures achieved by mLbL deposition further lead to improved antifouling performance.
